I went to 42+2 with DS. I was basically being forced into an induction at 42+3. My MW cited a study that proved the risks outweighed the benefits of staying pregnant after 41+3. (I do not have this info.) Nevertheless, they were willing to let me go to 42 weeks. They didn't care much for my choice to stay pregnant beyond that. As I said above, 42+3 was to be my absolute limit. They had me do a bunch of NSTs, an ultrasound, and I can't even remember what else after I went overdue. I was charting, so I am sure of my dates. DS came out with the classic signs of being overdue.
